I think that the 23.12 drivers are quite good with my GF2MX200. Slightly faster for me. I use Riva Tuner, but there are many things that it cannot do when compared to GTU. So, I go to guru3d.com and get both proggies, I run GTU to get the coolbits enabled and a few other settings, and Rivatuner for the rest. They complement each other in some ways
